Using Wireshark to Troubleshoot Network Connectivity Issues: Filters

In addition to the “Follow TCP Stream” feature, Wireshark also includes a powerful set of filters that you can use to narrow down the packets being displayed and focus on specific issues.

To use filters in Wireshark, simply enter the filter criteria into the filter bar at the top of the packet list. You can use a wide range of criteria to filter the packets, including the source and destination addresses, the protocol being used, and various other packet attributes.

For example, if you want to see only packets that are being sent from a specific IP address, you can enter “ip.src == x.x.x.x” into the filter bar, where x.x.x.x is the IP address you want to filter for. You can also use logical operators, such as “and” and “or”, to create more complex filters.

Filters can be especially helpful when trying to identify the cause of connectivity issues, as they allow you to focus on specific packets or types of traffic that may be causing the problem.
